Chronic myelomonocytic leukemia is a clonal stem cell disorder that is characterized mainly by absolute peripheral monocytosis. This disease can present myeloproliferative and myelodysplastic characteristics. According to the classification established by the World Health Organization, chronic myelomonocytic leukemia is inserted in a group of myeloproliferative/myelodysplastic disorders; its di...
AML1/RUNX1 point mutation possibly promotes leukemic transformation in myeloproliferative neoplasms.
Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders characterized by proliferation of one or more myeloid cell lineages. Some patients exhibit leukemic transformation (LT) by unknown mechanisms, and chemotherapy may increase the risk of LT. To clarify the molecular mechanisms of LT, gene alterations involved in LT from patients in the chronic phase (CP) of MPNs were...
Understanding leukemia heterogeneity is critical for the development of curative treatments as the failure to eliminate therapy-persistent leukemic stem cells (LSCs) may result in disease relapse. Here we have combined high-throughput immunophenotypic screens with large-scale single-cell gene expression analysis to define the heterogeneity within the LSC population in chronic phase chronic myel...
The P210bcr/abl protein is produced in cells from patients with Philadelphia chromosome-positive chronic myelogenous leukemia (CML). Retroviral transfer of the gene encoding P210bcr/abl into murine bone marrow induces a granulocytic leukemia that models the chronic phase of human CML. We have transferred the leukemic clone to syngeneic animals, albeit with surprising inefficiency, and have obse...
Background and Aim: Blood malignancies, one of the most common cancers in the world, cause a large number of deaths each year. Many inherited and acquired factors are involved in the development of this disease. Exosomes are a very small model of cells that are secreted by most cells in the body under physiological and pathological conditions. On the other hand, they have found a special place ...
Although microRNAs (miRNAs) are increasingly linked to various physiologic processes, including hematopoiesis, their function in the myeloid development is poorly understood. We detected up-regulation of miR-29a and miR-142-3p during myeloid differentiation in leukemia cell lines and CD34(+) hematopoietic stem/progenitor cells. By gain-of-function and loss-of-function experiments, we demonstrat...
The graft-versus-leukemia (GVL) effect in allogeneic hematopoietic stem cell transplantation (alloSCT) is potent against chronic phase chronic myelogenous leukemia (CP-CML), but blast crisis CML (BC-CML) and acute myeloid leukemias (AML) are GVL resistant. To understand GVL resistance, we studied GVL against mouse models of CP-CML, BC-CML, and AML generated by the transduction of mouse BM with ...
Donor cell leukemia after allogeneic hematopoietic stem cell transplantation might provide a unique human model for our understanding of leukemogenesis in vivo. We hypothesized that the "2-genetic-hits model" may contribute to the "leukemization" of donor cells and first evaluated these genetic mutations that are implicated in the development of acute myeloid leukemia in a donor cell leukemia p...
Abstract Background Polycythemia vera (PV) is characterized by red cell mass expansion in the peripheral blood and can be complicated with thrombosis, bleeding, evolution to acute myeloid leukemia (AML) or a fibrotic phase. Paroxysmal nocturnal hemoglobinuria (PNH) an acquired clonal haematopoietic stem disorder associated chronic intravascular hemolysis, venous defective hematopoiesis, frequen...
